Adopted the most advanced gel casting technology ,with high purity fused quartz as materials, this crucible has the characteristics of high original strength ,Unique homogeneous structure and slightly higher porosity, which will make the products have better thermal shock resistance and burst resistance.
Unique surface structure and appropriate surface roughness is specially suitable for spraying Si3N4, and the coating is not easy to drop off.
High precision crucible mold and its long service life make its products have good uniformity in size, which is easy to control the wall thickness precisely and uniform thickness from top to bottom so as to have better heat distribution within the hot zone during ingot crystallization, and also meet the requirements for crucible outer size and  improve the quality of ingots.
